MIPS: lantiq: Shorten register names, remove unused macros

Browse Source 
The macros LTQ_ICU_IM1_ISR and LTQ_ICU_OFFSET seems to be unused, remove
them. Allong with that, remove _IM0 substring from the macro names. The
IM (interrupt module) is already defined in IOMEM access and IM0 would be
misleading.
